The shaft C is provided with a rockingarm G, which at midstroke extends horizontally from the shaft, and a connectingrod H is pivoted to the arm, the latterhaving one or more pivot-holes G therein, a second or third hole being used for varying the stroke and theleverage.

A bracket Z is attached to the pump frame at one end thereof, preferably outside the frame, and to the bracket an intermediate lever I is pivoted at one end thereof having a pin-hole m, a suitable aperture being provided in the frame if the bracket be placed outside thereof, through which the lever may extend. The lover I has a' pivot hole 1) to which the rod II is connected, and it may also have an additional hole 7) for the same purpose, for also varying the stroke and the leverage applied to the pump-rod (or piston-rod) coupler J which is pivoted to the lever I and also to the pump-rod K. When the pump frame is suitably adjusted relatively to the suction-pipe or well-tube, if it be desired, the rod II may be connected directly to the rod K, and the lever I and the coupler J dispensed with. The lever I preferably has a plurality of pivot holes, as n and it also for varying the stroke and the' leverage for the pump piston. I

At the lower portion of the pump frame a combination pie fitting is situated, which comprises an 0 set pipe coupling and apacking box for the pump-rod I The fittin consists of a body part Land a branch If,

each preferably having an ear 9' whereby to fasten the fitting to a platform or timber. In the body part L above the branch is a.

erforate partition 1', above which is a packing-box a fitted with a packing nut t, the partition and the nut being adapted to per= mit the pump-rod to work therethrough.

The lower end u of the fitting is attached to the pump-barrel M which is attached to the cylinder N of suitable type having the -usual piston therein attached to the rod K. The

pump-barrel M is practically part of the dlscharge-pipe, although usually of some or suction-pipe M proper'below the cylinlength in the groun'd'When the cylinder is placed below the freezing line in the ground. A pipe too O is connected to the well tube der N, by a suction-pipe or nipple M, the Well tube or suction-pipe M extending down below the water line a: w in the ground, and usually having a perforated and screened. end portion M and point y; or, if the point to be omitted and the lower end portion be imperforate, it may have a foot-valve, as will be understood, an outer tube or casing being employed in such case. A suitable airhead P is usually employed in the bottom of the suction-pipe .or well-tube, as will be further explained hereinafter.

A dischargefpipe Q is attached to the top 1) of the branch L, and extends up in the pump frame. A tee 1 is attached to the pipe Q, and an air-pipe Q is-inountcd on the tee and extends up through the cap F, and is preferably provided with an airchamber It. A spout S is attached to the side of the tee 1, extending through a suitable aperture in the side A, and is pref erably provided with a stop-cock T.

The air-pipe U is connected to the top of thechambcr R (or with the pipe Q) and extends down through the cap F and the pump frame, and to and through the side branch w of'the tee O, and thence down'in the suction-pipe or well tube M to a suitable depth below the surface of the water basin in the ground, and is attached. to the airhead P when such is employed, as is preferable.- The connection with'the branch wis air-tight. Usually an air-cock V is attached to the chamber R. A platform V is employed upon which to set the pump frame.

The air-head P is preferably oval or eggshape at the body and lower portions thereof, and has a fiat top 2 having perforations 3, and also a central aperture having a flange '4 by which it is attached to the air-pipe II.

In practical use, the-lever 7: is moved up or down to operate the shaft B, it being designed in the present case thatthe lever should stand nearly vertical when the rod K is at the lower end of its stroke, so that it may not be an obstruction. hen the lever is drawndown to a position about the horizontal, the water will be raised. In the operation of the lever 70, the air that may be above the well water, both above and below the valve in the cylinder N, will rise into the air pipe and chamber and pass through the air-pipe U to the bottom of the well, or perhaps nearly so. In some cases it maybe desirable to'close the cock T or partly so, when starting the pump to work; and at times it may be of advantage to open the cock V either to admit air or to allow some air to escape, all of which may be better determined in practice. Should the water stand somewhat high in the pipe U, the air pressureupon it will force the water out at the air-head into and consequently up the well tube or suction-pipe with the aid of the piston in the cylinder N. At times, the water will rise and-fall intermittently in the pipe'U. in operation, the air sometimes passing out of the air-head P and by its pressure (even though but atmospheric) 'aid in lifting the water, and of course rising with the water to be again'returned, or to pass out of the spout with the water. In case the suction-pipe has a foot valve above the lower end of a perforated casing, the air ascending through the perforations 3 will directly assist in raising the ICS foot valve to admit the water into the sucsuction-p1pe,.a discharge-pipe connected with the cylinder, a spout connected to the discharge-pipe, and an air-pipe connected to the nipple and also with the discharge-pipe above the spout.
